Sure is. Use the log command

log [.]

This will output the message through the normal syslog configuration. An example of using the log command to output the HTTP uri would be as follows:

when HTTP_REQUEST {
  log local0. "Found uri: [HTTP::uri]"
}

The output will be in the /var/log/ltm file on the BIG-IP. This is also viewable from the GUI under the "System"."Logs"."Local Traffic" menu item.

Good luck!
